[PHP 5.2 with Apache 2.2] PHP can't found the activated extensions

Hello. For begin, I'm new on this newsgroup, and I'm French. I speak a little english, I'm sorry. My problem is on a Windows Server 2003 O.S. I want to run PHP as a module of Apache 2.2.6. So, I was edited the Httpd configuration for PHP 5.2: Action application/x-httpd-php "C:/php5/php-cgi.exe" LoadModule php5_module "C:/Php5/php5apache2_2.dll" AddType application/x-httpd-php .php .phtml .php3 .php5 AddType application/x-httpd-php-source .phps My PHP binaries are in C:\Php5\ The problem is here : PHP send me a multiple error messages: PHP Startup: Unable to load dynamic library 'C:/php5/ext/php_mysql.dll' - The specified module could not be found. But my activated extensions are in the C:\php5\ext\ directory! This is my PHP configuration : extension_dir = "C:/php5/ext/" All DLLs are founds in this directory. Can you help me please? Thanks! ;)
